Assemble set series Leonardo da Vinci studied the Guttenberg printing press and finely-tuned it for greater efficiency. In his design, da Vinci used a hand press with an automatic system that moved the type-saddle forward and back along a tilted surface. The forward movement and descent of the saddle are combined to make printing faster and easier.
